Exponential function:
Exponential function is function in which any exponent as variable raised over a constant
For exp:
![f(x)=(0.2)^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/auahc4k2if89f0orzgv4mj6vx17uq63lzh.png)
![f(x)=(7)^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/78oxoc67o6dqwlpwkqrkascahurjvr1tml.png)
![f(x)=(e)^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/iq3fcw7teppsljc5ez354x4xb6zsev1275.png)
here , 0.2 , 7 and e are constants
Power function:
Power function is function in which any exponent as constant raised over a variable
For exp:
![f(x)=x^2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/8ulmyaqupmet9k4hrc67ywwhiw279h9vbh.png)
